Furthermore, the dog has three at least and the equipartition is on the inside wall of the lantern ring.

Furthermore, the reciprocating mechanism comprises a driving disc and a cam, the cam is fixed on the driving disc, a guide plate is arranged on the driving disc in a surrounding mode around the cam, and a track groove is formed between the guide plate and the cam in a surrounding mode; the lower part of the thimble is provided with a bearing which is arranged in the track groove in a sliding way.

Furthermore, the poker bar is made of ABS, PP or POM.

The shuffling method with batch shuffling device in mahjong machine includes the following steps:

A. the mahjong pieces fall on the edge position, the middle part and the position close to the middle part of the big plate.

B. The big plate rotates, the clutch device controls the mahjong shifting strips to rotate synchronously with the big plate, and the mahjong on the edge of the big plate is carried away.

C. When the mahjong tiles at the edge of the large plate are detected to be carried away or reach the set time, the clutch device controls the mahjong tile shifting strip and the large plate to rotate relatively, and the mahjong tiles at the middle part and the position close to the middle part of the large plate are swept to the edge of the large plate by the mahjong tile shifting strip and then are carried away.
